Johnson and Wright ~hereafter J&W! claim, in their brief communication entitled “Reply to Philipona and O’Regan” that there are various difficulties in the reasoning in Philipona and O’Regan’s ~2006! paper entitled “Color naming, unique hues and hue cancellation predicted from singularities in reflection properties,” which was published in this journal in 2006. These difficulties supposedly pre...

The design of controllers for nonlinear, nonminimum-phase processes is one of the most difficult control problems currently faced. Current available control algorithms for nonlinear processes rely implicitly or explicitly on an inverse of the process. Linear control methods for nonminimum-phase processes are based on a decomposition of the process into a minimum-phase and a nonminimum-phase par...

An important step towards establishing an engineering discipline of software is to provide a formal basis for describing and analyzing software architectures. The Wright Architectural Speciication Language was developed for this purpose. The key novel features of Wright are its support for (a) formal speciication of new architectural connection types, (b) formal deenition of architectural style...
